i Application filed August 11, 1911i. Serial-No. 856,203.

To'aZZ whom 'it maj] concern Be it known that I, WILLIAM G. Buruma' a citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented. certain new and useful improvements in Adjustable Socket-VVrenches; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as w1ll enable others skilled in the art .to which it appertains to make and use the same.

My invention relates to wrenches, and more particularly to a wrenchwhich is adapted to use with nuts of various sizes. and without the necessity of making adjust,- ments, thus materially' reducing the cost of manufacture and at the same time reducin the liability of breakage.

In the accompanying drawings, which form part of this specification; Figure 1 is a longitudinal sectional view of the wrench in one of its operating positions. Fig. 2 is a similar view showing the wrench in another position, and F ig. 3 is an end view.

Reference being had to the drawings and the designating characters thereon, the numeral l indicates, a tubular member which may be of any desired form in cross-section, and the numeral 2 indicates a second tubular member preferably of the same shape as the tubular member 1, and of a size to permit i of its sliding freely therein.

rllhe tubular member 1 has one of its extremities enlarged as at 3, and near said enlarged portion 3, is provided with an opening 5, as shown in Fig. 1 and as shown in Fig. 2, a similar opening 5 is provided diametrically opposite the opening 5. Near the opposite extremity of the tubular memer l, are arranged a plurality of diametrically opposite openings 4 and 4c. The member 1 is also provided with a longitudinal slot 6, the purpose of which will be hereinafter set forth. v

. The-member 2 which as above stated -is freely slidable wit the member 1 has one of its extremities reduced as at 7, and near this reduced extremity 7 it is provided with diametrically opposite openings 8 and 8', while near its opposite extremity is provided wihgdiametrically opposite openings 9 an To the movement of the two menibers land 2 relatively to each other, a pin 10 is employed, pin being connected at 11 to the inner face'of the tubular member 2 and having its opposite extremit 12 projecting through an opening 13 andy into the slot 6, which prevents removal of the inner 'member 2. A pin 15 is used in connection with the device, said pin being adapted to be used as an operating handle.

When it is desired to use either the enlarged extremity 3 ofthe member l or the reduced extremity 7 of the member 2, the members 1 and 2 are positioned as in Fig. 1 andthe operating member 15 either in the openings 5 or 5 of the member l or the openings 8 or 8 of the member 2. When it is desired to use the opposite extremities of the members l and 2, they are positioned as shown in Fig. 2, and the operating member 15 inserted in the diametrically opposite openings 4 or 4.- diametrically the member 2.

1t is obvious that changes in the details of construction may be made without de parting from the spirit of my invention.

aving thus fully described my invention, what I claim is opposite openings 9 or 9' of 1. In a wrench, the combination with a' tubular member provided with a plurality of openings and a longitudinal slot, of a smaller tubular member slidable therein, and provided with a plurality of openings, a pin carried by said second tubular member and projecting in said longitudinal slot, and an operating handle adapted to be passed through the openings in either of the tubular members for engagement with the eX- tremity of the other tubular member to lock the tubular members against relative movement in operative position.

In a wrench, the combination with a tubular member provided with a plurality of openings and a longitudinal slot, of a second tubular member slidable Within the same and provided with a plurality of openings, a plin carried by the second tubular member an and .an operating handle adapted to be passed through the openings of either of said tubular members when the pin of the inner member contacts either extremity of said longitudinal slot, being adapted to engage the adjacent extremity of the tubular member by which it is desired to co-act with,and coperate with said pin and said longitudinal slot lock 110 of the member 1 or the projecting into said longitudinal slot,
